Covering over 200 square miles, the so called Windy City has a number of contradictions. For me, as I was walking the streets, I coined Chicago as New York but with manners ! But then you look at the murder rate; it's the highest in the USA !! Then you can say that the vacuum cleaner and roller skates were invented here. And the world's first skyscraper and cafeteria happened here. But then you read that Batman's dark fictional Gotham City was based on Chicago. And then you can sit back and listen to the police sirens all night !!
